mounted in a mine car wheel and Fig. 2 is a side View in quarter section of a slightly modified form of bearing. 1
In said drawing 5 indicates an outer bearing ring means while 6 indicates generally inner 20 bearing ring means. One of said ring means is formed in separable parts and in the form shown the inner ring means 6 comprises two separate inner rings or ringparts 'l-8, which are axially aligned and preferably arranged in end-abut- 5 ting relationship to each other. The outer ring 5 is provided with spaced-apart angular contact racewaysjQ-Q, the angles of contact converging outwardly of said ring. Each of the inner ring parts 1-8 is provided with an angular raceway ll], complementary to the two raceways 9-9.
the ends, as indicated at l2-l2, and a coupling 45 sleeve preferably in the form of a spirally coiled spring I3 is passed over the surfaces |2--I2, which spring, due to its inherent resiliency, serves to frictionally couple the ring parts 1-8 together.
I 50 By rotating the ring parts l-B relatively to each other in a direction to uncoil the spring I3, the ring parts 1-8 may be quite readily separated from each other and during assembling the ring parts 1 -8 are likewise preferably rotated 55 relatively to each other, so as to tend to uncoil the spring l3 and thus facilitate assembly of the rings.
It will be seen that in a bearing as thus far disclosed the operations of filling the raceways With balls or the assembly of balls in cages with the raceways and the subsequent assembly of the inner and outer rings with interposed anti-friction bearing members are all relatively simple operations. I
If disassembly of the bearing becomes neces- 10' sary such disassembly may be readily effected, as stated, by slightly rotating the rings l8 relatively to each other in a direction to uncoil the spring,thereby releasing its grip, and then pulling: the two rings outwardly so as to separate the same. I
In the form shown in Fig. 2 the inner ring is provided with outwardly extending flanges I l-45 which extend into relatively close proximity to the adjacent inner side of the outerring 0 and in effect provide ahoused or sealed bearmg.
In the form shown in Fig. 1 the inner ring parts are not provided with integral flanges but a separate felt seal It is carried by one of the rings, such as the inner ring, and seals the space between the inner andouter rings.
Fig. l illustratesone form of mounting for the bearing, in which ll indicates a mine car wheel or the like, which is counterbored, as indicated at l8, for the reception of the outer bearing ring 5. The inner ring parts 1-8 are mounted on the end of the shaft or axle l9 andare rigidly secured between the abutment collar 20, engaging the shoulder 2| on the axle or shaft, and the cated at 25, so that if the two rows of balls do i not hold the rings in strict axial alignment there will be no sharp shoulder for the end of the shaft It) to engage and prevent the slipping of the inner ring onto the shaft. The chamfered or tapered edges 25 readily ride over the end of the '50 shaft, so that the bearing may be assembled with the shaft with substantially the same ease as if the inner ring were in a single part. When the inner ring is assembled with the shaft l9 and secured in place thereon, the two ring parts 1--B are rigidly held together and act substantially the same as if the inner ring were in one part. All parts of the bearing are exceedingly simple and cheap to manufacture and the completed bearing is quite serviceable and for many uses is fully as good as the more expensive types of bearings. The coupling sleeve I3 is positioned between the two rows of balls and in the space between the inner and outer rings, so as to be invisible from the outside and so as to be out of the way.
As shown the length of the sleeve is such as to space the ring parts 'l--8 apart sufiiciently during the operation of filling the raceways with balls so that when one raceway is filled the hearing may be turned over and the other racewayfilled, after which the two parts 'I8 may be crowded toward each other into final position Where they will be frictionally held for safe packing and transportation.
While the invention has been described in considerable detail and preferred forms shown it is to be understood that various changes and modifications maybe madewithin the scope of the invention as defined in the appended claims.
